Flu activity in the United States remains high and will continue for several more weeks, the Centers for Disease Control and Prevention said on Friday. This year's flu is severely affected by people aged 50 to 64 years old. One possible reason is that an event is called to print. The first influenza virus, which is exposed to a child, is the method of determining how influenza will react in the future.

This flu season is considered highly serious by the Centers for Disease Control and Prevention, but an age group is feeling more than
CDC told reporters on Friday that people of the age group of 50 to 64 years are particularly affected badly by this year's flu. This can be due to strains in circulation, while the major stress is green H3N2, which is less well-protected than the flu vaccine, H1N1 is also sending the child's diseases to the hospital.
One possible reason, the CDC's Dr. According to Dan Jarnigan: An event called the Printer
In the national center of CDC immunization and in the National Center for Respiratory Diseases, Jerinigan, director of influenza division said, "You can respond to influenza for the rest of your life by way of determining any influenza virus coming out in the form of a child. . "
In 2009 with H1N1, for example, "We have seen a small number of people recruited at the age of 65", he said. This tension first emerged in 1918. "From 1918 to 1947, when the H1N1 was circulating, the people who were in contact with that one, it seemed to give a better response when this 2009 H1N1 showed up back," Jarnigan Explained
In the 50-64 age group, there are no people related to that stress, so it may be that there is no protection like the old ones.
"There is still a lot to learn about it," said Jarnigan, "it reflects the complex nature of influenza."

For the major H3N2 tension in transmission this season, which first arose in 1968, Jarning said. And since then, and continues to evade the human immune system, since then.
"It really depends on the mix of things: the environment, the virus itself and how it changes," and he said, "the host."
